<span>common difference for the sequence = 1/16
cause
1/4 = 4/16
and
3/8 = 6/16
so
4/16 + 1/16 = 5/16
5/16 + 1/16 = 6/16

15 times 3.14
Answer:
60
Step-by-step explanation:
Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
16,700,000,000,000,000 = 1.67 x 10^16
start at the last 0....count the number of spaces till u can get a decimal right after the first digit....thats 16 spaces. Now take ur numbers that are not 0...1.67....and multiply it by 10^16...because of the 16 spaces. I hope I am making some kind of sense...I am better at doing then explaining how to do...lol
